To all whom it may concern:

Be it known"that I, JAMnsM. Wonrn, a citizen-of the United States,residing at Chi; cego, county of Cook, andv State of Illinois, haveinvented'certain. new and useful Improvements in Gas-Engines; andI'deelare the following to be e fulheleztr, and concise description ofthe same, reference being had to the accompanying specification anddrawmgs. Y

My purpose is'to produce a geseng'ine wherein an explosion takes placeat eahend of the working cylinder at every complete cycle'of motion,pi'ocuringthereby practically as the source of energy.

thesaine result as obtained in the use of all single cylinder steeimengine. I have designed to use either generated gas or gnsoleneReferring to the drawings, Figure 1, is the side of one side elevationon an engine em bodying my invention. Fig.2 is-a central. verticalsection of same, taken lengthwise of the cylinder and on theline 22 ofFig. 8.

The action of my engine wlllhe described as it-operetes when generatedgasis needle-s It-will he that as thepiston D. time in the cylinderB',,II1OVG S to the left a certain amount of gas will be drewnintei thechamber B from the gas-chamber B through the puppeirvali'e B At the sametime acertain amount of air will be drawn into the chamber Bf throughthe vulve'B, plncedin the right cylinder-heed BI. The return of the gasand air thus admitted is prevented by the puppet-valves B" B. As thepiston starts on its return stroke the earbureted air will Us compressedin the chamber B, the puppetvelve D will beopen and the cerburetedia iiwill pass into thehollow piston D wherefit stantially asr shown in Fig.2.

The piston E on itsreturn stroke toward theleft will out oh? the port or passage C andexhaust-port C and compress the carhureted air within the [O chamber C.

As the piston E nears thelimit of. its stroke the spying-eleetrodeE willconin the cylinder (3.

a spark produced that will ignite the gas and caifse an explosion whichwill force the piston to the extreme limit of its travel toward theright, uncover the exhaust-port, and allow the expanded gas to escape tothe atmosphere through the exhaust-port C and exhaust-pipe 0'. Theaction-is the same in the chambers 13 C as in B C, an explosion takingplace in each combnstion-ehamher at every rerun-ocelion of the pistonsl) E. The piston D is rigidly conneoted to the piston E by means sublhisconnection insuresa corresponding stroke to the two pistons; The "elinder C is provided with longitudinal slo s l to allow the crank-armconnectionaml-wrist-pin to pass to and 'frox' These slots also allow airtopass into the piston through the corresponding slots E in the sidesthereof, thus aiding in reducing the temperature due to the heat causedby the ex'plo sions.
